When the antenna sensor has been attached, covering the whole of the
bumper from left to right, the excess length is cut off. Place a piece of the included
sticking material at either ends of the antenna sensor to ensure a secure fixing
onto the bumper surface.

2.0
It is recommended (but not essential) to cover the antenna with a black anti-rust
protection paint of the same type that is applied to the underneath of a car chassis
or similar to protect from the elements (do not use silicon paste).
Sticking material
EPS-DUAL 2.0 can be installed only on rear bumper.
The sistem is strictly a driver assistance device and should not be relied upon as a
security device or a substitute for safe driving practices.
Use common sense when reversing and always follow recommended safe driving guidelines.

a) The installation of the antenna sensor, constituted by an
aluminium adhesive ribbon, must be performed to the inside of the bumper.
It is of some importance that the zone of application on the inside surface of
the bumper corresponds to the higher part as regards the ground but also
the most distant from the car body. It is not advisable to install the antenna
sensor too low.

Connect the RF Cable coming from the ECU to the antenna sensor.
Apply a piece of sticking material on the connection and fix it on the bumper by a
strong pressure (If the ambient temperature is below 10 °C we recommend
heating both the mastic and the sticking area on the bumper). It is necessary to
use the same material to fix the opposite extremity of the antenna. (Fig. 5).
Replace the bumper and pull the RF Cable inside the luggage compartment or
engine compartment in order not to leave excess cable outside.

STARTING PROCEDURE
Fig. 5
a) Identify on the car body the zone close to the extremity of the bumper and, on
the side where it is present the back-gear lamp, a possible hole of passage
toward the intern of the trunk in order to carry out the RF cable from the antenna
sensor.
b) Through the individuated passage route the RF cable inside the trunk
leaving the fast-on terminal outside. (Fig. 2)

ELECTRICAL CONNECTIONS
a) Connect the red lead of the power cable to the positive cable that feeds
the reversing lamp.
b) Connect the black lead of the harness to the earth of the reversing lamp.
-- IT ADVISABLE NOT TO CONNECT TO ANY OTHER POINT OF EARTH ON
THE CHASSIS OF THE CAR -c) Insert all plug-in connectors into the proper position on the Central Unit (ECU)
as in Fig. 6.
Cable RF
Fig. 2
Some vehicles are equipped with a metal crash protection bar insert facing the
inside surface of the bumper. When this metal surface is too close to the inner
surface of the bumper where you have placed the antenna sensor, the distance
signal can be reduced.
To adjust the signalling distance it is sufficient to change the dip-switch positions
(see schematic on next page). Take care that the sensitivity No 1 is the lowest
and the number 4 is the largest.
The sensibility that we recommend for most cars is the No. 2.

MOUNTING THE ANTENNA SENSOR
Thoroughly clean with alcohol or nitre solvent (be careful not to use antiadhesive detergent) the inner surface of the bumper of the zone previously
identified (see Fig.1) on which will be applied the antenna sensor.
Starting from the zone where there is the RF cable , start applying the adhesive
aluminium tape (antenna sensor) practising a good pressure to make it well
adhere to the inner surface of the bumper *.
We suggest to carry out tests to determine the detection range, pointing out that
increasing the sensibility where it is not necessary, can cause more false alerts.
MOUNTING THE SPEAKER
a) Mount the EPS-DUAL 2.0 speaker using its adhesive in a proper place in
order to ensure a good perception of sound by the driver.
b) Connect the buzzer cable to the buzzer through its plug-in connector.

FINAL TESTING PROCEDURE
Antenna sensor
a) Turn on the key, insert the back gear. In a fraction of second the control unit
performs a check of the functionality of the system and, if everything has been
done correctly, the transducer emits an acoustic sound of "OK" (two notes in
rapid succession). Once you have this signal the system becomes operational.
Bumper

Possible problems and their solutions
1. If the acoustic transducer does not emit any signal check all the connections.
2. If the transducer emits an audible warning signal consisting of 2 notes (one
high and one low) repeated 3 times) check the connection of RF cable.

ALARM SIGNAL
RISK OF CONTACT SIGNAL
b) Starting from about 1 meter away from the center of the bumper, slowly
approach both hands to simulate a parking maneuver. At a distance of about
60/70 cm will be heard the first acoustic signals whose repetition rate will
increase at the decreasing distance to become a fast intermittent sound fast and
then a contnuous higher frequency sound at about 10-15 cm from the bumper.
WARNING: For a correct simulation be careful to reset the system every time
you approach.
c) If the system shows to work regularly it is possible to fix definitely the bumper.
Note: EPS-DUAL 2.0 starts to give the signalling only when the vehicle is being
approached to the obstacle; a fixed object in front of the bumper, for instance the
hauls hook and a bull bar or the sides walls of a car box, is not signalled and it is
not bothered the normal operation of the device.

USER MANUAL
OPERATING PRINCIPLE
Central module
(ECU)
1
EPS-DUAL 2.0 is an innovative parking sensor that uses low energy
electromagnetic waves and is able to detect the approach of any kind of
obstacle.
The activation of the device is obtained by the insertion of the back gear and
confirmed by a signal of “OK". Once activated, the EPS-DUAL 2.0 generates
around the bumper, on which is installed, a protection zone (Fig. 6).
When any obstacle present in the protection zone tends to approach the bumper
you will hear a series of beeps.

WORKING EXAMPLE
B) When approaching an obstacle the system activates the acoustic signal at
a distance between the bumper and obstacle (measured in the central area of
the bumper) of about 60 / 70 cm with 3 types of sounds:

A) As soon as the EPS-DUAL 2.0 is activated the control functionality of the
system is carried out in a fraction of second.
In case of anomalies the speaker emits an audible warning signal consisting of 2
notes (one high and one low) repeated 3 times. If this happens check the
antenna connection to the ECU.
If the control is OK you hear a signal of two notes in rapid succession to confirm
the proper functioning of the system. If installed on the front bumper the OK
signal consists of a single note.

TECHNICAL CHARACTERISTICS

- Operating temperature from -20 to +90 °C
- Max. Distance to begin detection 70-80 cm
1) an increase in sequence of "BIP" (alert) informs the driver that an
obstacle is approaching.
2) intermittent sounds of fast repetition rate when the obstacle comes
close to the bumper at a distance between 15 and 30 cm measured on the
middle of bumper (alarm).
3) continuous sound at a more acute frequency (risk of contact) when an
obstacle is very close to the bumper (10-15 cm).
Central module (ECU)
Buzzer cable
Note:
- The distances will vary depending on the size of the obstacle and
correspond to the central zone of the bumper; on the lateral edges the
distances is less (see Figure 6)
- The alert occurs only when the vehicle is approaching an obstacle, a fixed
object in front of the bumper is only detected after the first movement of
approach.
WARNING
1. In presence of rain or high moisture weather, the system reduces his
sensibility automatically in order to eliminate a part of false alarms that could be
given by movement of water on the bumper.

2. As soon as the system is activated an acknowledgement of the surrounding
of the bumper is made.
Consequently it is very important, during testing operation, not to switch on
the system while you are very close to the central unit and antenna sensor in
order not to have false information on the working capability of the system.
Sticking material
Antenna sensor
During the test you must also take into consideration the fact that, after the first
approach to the bumper, any subsequent APPROACH without first reset the
system, can give false interpretations of the functionality of the sensor due to
special characteristics of the EPS-DUAL 2.0 software specifically created to
reduce false signalling in the rainy conditions.
